I work at a company where we have to make outbound calls. The following numbers just pick up and beep once. It acts like an instant voice mail and it proceeds by beeping a couple of times then hangs up. Just wondering what this could be and thought I would share this interesting find.
573-234-1999 - Rings now. Must have been during a down time. Unknown why but working normal now.
Are there any numbers that answer with dead air and hang on the line indefinitely when called?
